-improved structure that is ca ab e of securing the two-fold effect of friction due to rubbing the human skin by a bristle brush and the pricking effect of jets of Water (either hot vor cold).

My invention includes various novel features. According'to my invention a spray tube is provided having jet perforations facing the bristles or iuidabsorptive rubbing portion so as to direct a spray u on the fluid absorptive rubbing portlon.` ccording to my invention this spray .tube is located eX- teriorly of the Huid absorptive rubbing portion and directs its spray toward the surface of the Huid absorptive rubbing portion.

According to my invention, the spray tube and valve are combined, com rising two tubular parts, one within the other land one rotatable axially relatively to the other, and the valve operation is effected by such rota-l tion of one of the parts, a cross-bar or gripping iece being located in proximity to the hand e. According to my invention soft and rough rubbing surfaces are provided to be used as required.

The improved brsh is especially well adapted to restore or establish ood circulation in any part of the human ody, and in use thefbrush is kept in a clean sanitarycondition by the waterbeing su plied to the bristles and to the skin of t e user, thus making the water ilow over the body of the user'when the brush is rubbed against the skin,'and also preventing splashing of the needle-spray, so' that it is possible to ta'ke a bath in a narrow place or vessel without y wetting the floor.

.The parts of the brush are so combined and arranged that sharp metallic projections are avoided which may have a tendency to N tear, scratch or injure the skin.

With the brush is associated a novel form of valve that is easily manipulated and which is arranged to shut oil' the water su ply or to direct the s ray to the soft o1' roug surfaces of theV brusii. i

I avoid the employment of reservoirs, and

produce a brush of light, simple construction which can be handled with ease and facility, by making the handle in the forni of a hollow core or tube adapted to have a hose or iiexible tube connected thereto, for supplying water to the needle-spray. Provision is also made for the application of an electric current to the body by the provision of an elec-` trically conductive spray tube and means for connecting asource of electric current to the spray tube so that the jets of water will conduct the electric current to and through the wet Huid absorptive rubbing portion and to the body of the user, and by the provision of v an insulated handle so that the electric current will be applied only at parts to which the rubbing surface of the brush is applied.

With these ends in view, the invention consists of the novel construction and combination of parts, which will be lhereinafter fully described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.A

Figure 1 is a side elevation partly broken away and in section, of a bath 'brush embodying my invention; Fig. 2 is a longitudinal sectional view on the line 2 2 of Fig. 3 through the improved bath brush; Fig. 3 is a sectional plan view, the plane of the section being indicated by the dotted line 3-3 of Fig. 2. Fig. 4 is an enlarged cross section on the line 4-4 of Fig. 1 through the tube and the regulating valve, the rest of the 'brush being omitted; and Fig. 5 is a detail view of one formof a double water coupling which may be used in connect-ion With the improved brush to supply hot or cold water' thereto. Fig. 6 is a view, partly in perspective, illustrating means wherebyan electric current may be supplied to the person ofthe bather when water flows through the ini-` proved brush.

The handle 5'is referably of cylindrical form, and at one en it is enlarged toproduce a head 6, the latter being provided with.

sockets or recesses 7. The handle 5 and its head 6 are rovided with a longitudinal passage 8, an firmly secured one end portion of the needle'- spray tube 9, the latter extending a suitable distance beyond the head and occupying a co-axial relation to the handle. The outer end of the tube 9 is closed in any suitable way, but this tube is provided 'with rows of spray openings 10, 11, the same being arranged to face in opposite directions, as indicated more clearly by Figs. 3 and 4. It will be understood that the spray openings 10, 11, are provided in that part of the tube which is extended beyond'the head of the handle, and this projecting part of the spray tube is adapted to support the means employed by me to hold the soft and harsh ristles which form the soft and rough facesl respectively of the brush. I employ two rows of coarse bristles, indicated at 12, 13, and corresponding rows of soft bristles, indicated at 14, 15, and one row-of coarse bristles is arranged to have interlacing relation to the row of adjacent soft bristles, thus the' bristles 12 and 14 are interlaced, while the bristles 13 and 15 are.. interlaced, as shown more clearly by Fig. 3. The .rows of bristles are fastened in any suitable way to cores which are preferably of metal, and in the manufacture of the brush, I prefer to employ cores of wire which are twisted together to form strands adapted to grip and hold the bristlcs'of the brushes. The strands forming the cores of the bristles 12 14, are indicated at 16, while the strands forming the cores for the coarse and soft bristles 13, 15, are indicated at 17, in Fig. 3. The cores for the bristles 12 14 are made from pieces of twisted wire which are doubled upon themselves, and in asimilar way the wires forming .the cores for the bristles 13, 15, are doubled so that each core will sustain a row of coarse bristles and a row of soft bristles.

The metallic cores of the rows of bristles are fastened to bridge pieces or cross' heads 18, 19, the former of which is secured in any suitable way to the outer end of the perforated s ray-tube 9, while the other cross head or ridge piece is attached to the spraytube at a point quite close to the head 6 of the handle. This cross head 19 is provided with downwardly inclined portions 19, see Fig. 1, and at the lower ends of said inclined portions of the cross head are fastened the ends of the strands forming the cores of the bristles. The ends of said cross head and the ends of the core strands are extended into and fixed in the recesses 7 of the head 6,.and

the metallic parts of the brush are thus housed within the head of the handle in a wa to prevent them from scratching, tearing or A in the handle and its head is open through the latter on lines between the two sets of bristles 12, 14 and 13, 15,.respec tively, whereby jets of water issue in the form of a spray from one side or the other of a brush according to the adjustment of an internal valve tube 20. This valve tube is arranged snugly; within the jet tube 9 a'nd it extends throuvf said tube 9 and the passage 8 of the handle, one end of the valve tube extending or projecting beyond the handle fora suitable distance, as shown by Figs. 1 and 2. length of the brush and it is provided with a. slot or waterwa `21, the latter extending longitudinally o the valve tube for `adistance equal to thelength of the series of jet The valve tube thus extendstthe full openings in the perforated tube 9. The

vided with a cross bar 22 which is adapted to be gras ed by the fingers in order to rotate said vave tube within vthe handle or the spray tube, and toA this extended end of the valve tubeis ada tedto be coupled-means for supplying the Brush with hot or cold water, as may be desired. A flexible tube or hose 23 may be attached to the exposed end of the valve tube 20, and this tube may have a single suitable connection 24, shown by Figs.

1 and 2 ,which may be fitted on either a hot or cold water faucet. Inlieu of using the single water tube, I may employa double water tubehaving thelegs 25, 26, united by aT coupling 27, and these legs are rovided with t connections 28, shown by i 5, which may be fitted on the hot water an the cold water faucets respectively, thus making rovision for sup l hot or cold Water to t e valve tube oftlildlrush. v

1f it is desired to supplya current of electrical energy to ,the body when the bristles are saturated with water, an electrical conductor 29 may be clamped in a binding post 30, which is secured to the projecting end of the metallic valve tube 20, the latter thus serving in part as a conductor for the electrical current. The electric circuit is shown by Fig.y 6, the same including abattery 35 and an electrode 36. This electrode is represented as a fo'ot-V late on which the bather should stand, an the electric circuit is comleted through the body of the bather, the brush and the foot-plate, although I reserve the right to form a complete circuit in any equivalent way. The handle 5 and the head 6 are made of hard rubberin order to serve as an insulator to the tube 20 in the application of the electric current, and this handle is preferably provided with a ribbed or corrugated surface 31, thus preventing the brush from slipping in the hand when using it in soapy Water.

ln using the improved brush, one of the tubes is connected with the faucet and the valve tube 20 is adjusted to direct the spray through either grou of openings on the coarse and soft side o the brush. The brush is rubbed frictionally against the skin and the spray is directed in needle like jets against the body, thus securing at one and the same operation the beneficial effects of the frictional rub and the spray batl1.- The `valve may be conveniently manipulated at any timeto change the course of the iiow of water through the brush, or the valve may be turned ina direction Whi'ch will bring the Waterway 21 opposite to a non-perforated part of the tube 9, thus cutting ofi the flow of Water.

It is evident that any suitable substance may be used in lieu of hard rubber, to form the handle and serve as an electrical insulator, and that the bristles when worn may be re laced by fresh or new bristles.

aving thus described* my invention, I claim as new and desire to secure by Letters Patent,-
